Description

Technical Field

[0001] The present application relates to the technical field of rotary seeders, and in particular to a device for synchronously adjusting a pressure roller and a mud scraper blade of a rotary seeder in parallel up and down. Background Art

[0002] As an important agricultural machinery, the rotary seeder occupies a key position in modern agricultural production. With the continuous advancement of agricultural technology, the application of rotary seeders has become more and more extensive. It integrates multiple functions such as rotary tillage, soil crushing, land leveling and sowing, which has greatly promoted the development of agricultural production towards high efficiency and scale. This integrated operation mode not only significantly improves the efficiency of agricultural production, but also effectively improves the degree of soil compaction, which is of great significance for protecting soil structure and improving the growth environment of crops. At the same time, it also saves farmers a lot of time and labor costs, and promotes the sustainable development of agricultural production.

[0003] In actual agricultural production, due to the differences in soil quality in different regions, in order to ensure that the soil reaches an appropriate degree of compaction, it is necessary to adjust the height of the pressure roller in the rotary seeder. In addition, in order to ensure that the scraper can effectively scrape off the soil attached to the pressure roller, the height of the scraper also needs to be adjusted accordingly. At present, the conventional adjustment method in the industry is that the operator first uses an external machine to support the pressure roller, and then manually removes the fixing screws on the pressure roller to separate the pressure roller from the rotary seeder. After that, the height of the pressure roller is adjusted using an external machine. After the adjustment is in place, the pressure roller must be re-fixed on the rotary seeder with the fixing screws. The height adjustment method of the scraper is similar to that of the pressure roller, and it also requires cumbersome disassembly and adjustment steps. The entire adjustment process is extremely cumbersome, which affects the adjustment efficiency of the pressure roller and the scraper, and needs to be improved. Summary of the invention
